I think it takes a lot to "move a toilet" however perhaps it was an older device with rusted mounting bolts? 

I will look into putting in electric heaters, putting in propane wall mounts, and getting separate boilers and oil tanks for each of the units.

When the fans attached to the motors get old they can come off axis as they are spinning off level.

It avoids the problem of repairs mounting up in excess of the deposit, and is also "trains" the tenant to take better care  of the property.

There is, however, evidence that dirty heating and cooling coils, motors, and air handling units can make your HVAC unit less efficient.http://www.todayshomeowner.com/hvac-duct-cleaning-...

PS> I have a 2014 BMW S1000RR Look it up/ If a tenant ever left any type of motor vehicle I'd be thrilled! 

The issues you're facing are not just real estate related, they're relationship related and no one here is qualified to solve the mounting issues you're facing. 

They are a necessary tool for that individual to function on a daily basis, similar to a motorized wheel chair.

I also believe many people might find it more convenient to wait until their current out-of-state license expires before enduring the fun and joy that is to be had at the Division Of Motor Vehicles.If everything else checks out, it wouldn't raise a red flag for me.

I was just pointing out that I haven't heard of obese people as a protected class.However, I will say that many businesses and hospitals are starting to replace wall-mounted toilets with floor-mounted toilets in public bathrooms.
